CIL & Developer Contributions Cardiff

Land Use and Zoning Wales 3 Minutes Read ยท published February 12, 2026 Flag of Wales

Overview

Cardiff, Wales operates a planning contributions framework that combines the Community Infrastructure Levy (CIL) with planning obligations (Section 106) to secure infrastructure, affordable housing and other site-specific mitigation from development. Developers should identify CIL liability and possible Section 106 requirements at pre-application and application stages, and use the council guidance and charging schedule for charge rates, exemptions and reliefs. See the council CIL guidance for local policy and implementation details Cardiff Council CIL page[1].

Discuss CIL and contributions with planning officers at pre-application stage.

How CIL and Developer Contributions Work

CIL is a non-negotiable, schedule-based charge on liable development unless relief/exemption applies; Section 106 agreements are negotiated obligations tied to planning permission. The planning authority allocates CIL receipts for infrastructure and may pool S106 obligations for on- and off-site mitigation. For the council's explanation of planning obligations and S106 agreements see the planning obligations guidance Cardiff Council Planning Obligations[2].

  • Liability and relief: identify if social housing, charitable development or small-scale exemptions apply.
  • Timing: liability is typically calculated at permission or commencement as set out by the council.
  • Specification: S106 sets site-specific obligations such as affordable housing, highways works or open space.

Penalties & Enforcement

Enforcement and recovery for CIL and S106 are managed by Cardiff Council planning and enforcement teams; specific sanction amounts and recovery procedures should be confirmed from the council guidance and enforcement contact pages. Where the council page does not list fixed penalty amounts or escalation bands, the exact figures are not specified on the cited page and may follow statutory CIL regulations or separate enforcement policies Cardiff Planning Enforcement[3].

  • Monetary penalties: not specified on the cited page.
  • Escalation for repeat or continuing breaches: not specified on the cited page.
  • Non-monetary sanctions: enforcement notices, stop notices, injunctions or legal recovery actions may be used where obligations are not met.
  • Enforcer: Cardiff Council Planning and Enforcement teams; complaints and investigations are handled by the planning enforcement contact route.
  • Inspection and complaints: use the council enforcement contact page to report non-compliance or request inspection.
  • Appeals/review: appeal routes and statutory time limits are not specified on the cited page and may follow statutory appeal processes; check official guidance or request written decision notices from the council.
If you are unsure whether a development is liable for CIL or S106, seek written confirmation from planning officers before starting works.

Applications & Forms

The council publishes guidance on liability, relief and responsibilities; specific application or claim forms (for example for exemptions or relief) should be obtained from the Cardiff CIL and planning obligations pages. If no specific form is published on the council pages, the council usually requires written claims or standard application forms as described on those pages, otherwise the exact form name or number is not specified on the cited pages Cardiff Council CIL page[1].

  • Before submitting a planning application, review the Cardiff CIL charging schedule and S106 guidance.
  • Submit any required claims for exemption or relief with supporting evidence as directed on the council pages.
  • Contact Cardiff Planning or Enforcement for clarification or to report suspected non-compliance.
  • Pay any invoiced CIL charges or agree S106 contributions by the council deadlines to avoid recovery action.
